    Courses Two of the required courses in the same time slot

    Hi, I just discovered that next year, i will have two courses in the same time slot. I supposed to take one of them (statistical physics) this year (third year) but due missing prerequesite which I'm taking now, I'm unable to. These courses are offered only once a year. i can't graduate next...

    Comp Sci C/C++ hw question

    & is the bitwise and operator, x &= x-1; is the same as x = x & (x-1); if an unsigned int x = 5; then 5 = 101 in binary and (x-1) = 4 = 100 so after evaluating, x = 100 in binary or x = 4 in decimal.

    Pigeonhole problem set

    I got it now, at first i thought the question requires you to take the number of combination of the set A in account. thx

    Pigeonhole problem set

    the number of subset of A of length 5 is 126. there smallest sum would be 1+2+3+4+5=17 and largest 25+24+23+22+21 = 115.

    Photon striking material

    hi, From what i understand is that photons lose engery after being reflected off some material due to conservation of momentum (hitting electrons...). If they loses energy then their frequency is smaller, but how come when u look at a mirror you don't see a change in color the image in the...

    Aero, EE, ME? which one is fun?

    In my opinion, i would say aerospace engineering is the best. You get to design and play with all the nice toys (airplane, rockets...). ME is ok.. but stay away from EE. not fun from what i heard..

    Moon and tides (tide on the moon instead of earth)

    Just to add, if it's not a trick question, the answer is "never". The same side of the faces the Earth all the time, so there would be no tide. that's what i thought too, since the high tides remain in the same place, the period wouldn't exist... btw this question is from first level...
